And why bother learning Workbench? Setting aside all its surface and CCF/HCP functionality (and that's a lot to set aside), I think the ability to create "scenes" justifies the time spent learning the software.

This screenshot shows scenes in action: clicking the little button marked with yellow arrows brings up the scene dialog box. I have three scenes stored in this file, and selecting one for display changes Workbench to recreate exactly how it was when the scene was created: window size, colors and scaling, loaded images, tab layout. Creating scenes for each image that might be used in a publication can save massive amounts of time: need to adjust a threshold or change a color? Just bring up the scene and make the change, no need to start from the beginning.

UPDATE 8 February 2018: linked to the new volume to surface tutorial; fixed the official tutorial link.
UPDATE 2 August 2017: removed the (very outdated!) mention of the release of Connectome Workbench 1.0; renamed this post to the more general "Connectome Workbench: 1st Steps".
